To all whom) it 1711a, concern: Be it known that I, ALANSON P. BRIJsH, a cltizen of the United States, residing at Detroit, county of Wayne, State of'Michigan,.

have'invented a certain new and useful Improvement 1n Jacketing Systems for Enginehad to the accompanying drawings, which form a part of this ,specification.

My invention has for its object certain new and usefulin provements in the construction of engines, and relates. more particularly to the construction of internal-combustion engines, the specific objects of my more especially to the provision of a water-jacket wall for the engine cylinder or cylinders in connection with related parts of the engine. I

I'carry out my invention as hereinafter described and claimed, and illustrated in'the accompanying drawings, in which- Figure l is a view of the water-jacket and parts being in section. Fig, 2 is a snnilar'view, but showing various partsbefore they are assembled. Fig. 3 is an end view of the cylinder.. view in section of a cylinder and its adjacent water-jacket wall.

Asregards the water-jacket wall, my inj vention is designedto provide an enginecylinder with a j acket-wall of superior construction, efficiency,and durability, the water- My improved water-j acket wall is intended to be made of thin soft metal, the same being constructed at 'theend thereof adjacent to the frame of the engine with an outwardlyturned flange, (indicated at g.) At its opposite end the jacket-wall is formed with an inwardly-turned flange, (indicated at h,)

the wall being spaced from the enginescylinder to form a water-chamber therebetween,

(indicated at L), The cylinder of the engine (indicated at 02,)

Fig. 45 is an enlargedder is cored :out torp is forined with a discharge-channel j, com

municating with the water-chamber c at one endthereof andat the otherextremity with one or inore'inlet-channels is, communicating with said water-chamber. The cylinder is formed with an outwardly-projecting flange (indicated at Z) at one end thereof, against which; the outwardly-turned flange g of the jacket-wall seats. 'To clam the flange g of jacket-wall upon the flange Z I employ a clamping-ring m, held in place to clamp the flan j acket-wall between it and the flange Z of the cylinder in any suitable manner.

In the drawings I have shown the frame of the engine provided with a series of studs,

the clamping-ring and held'in engagement of the cylinder, said ring being ge g of the said studspassed through therewith by nuts p. It willbe obvious that the ring m thus, together with the studs ,n

. and the, nuts p, not only clam the flange g of ring and the the jacket-wall between sai flange Z, but at the same time they unite the' end of the cylinder with the frame of the en glne. made of soft metal, it is obvious, serves as a gasket, as alreadyindicated. The inwardlyflhe flange g ofthe jacket-wall being turned flange h at the opposite end, of-the jacket-wall is held in place etween theiadjacent end oft-he cylinder and theadjacent end of the wall of the valve-chamber 0.; The engine-cylinder is preferably constructed with an inwardly turned flange, as shown, at the.

end thereof adjacent to the, valve-chamber, the inwardly turned flange of the waterjacket being clamped between the waterjacketed valve-chamber and the inwardlyturned flange on the adjacent end of the cylinder. 'I hevalve-chamber 0 may be united with the. adjacent .end of the cylinder by means of a threaded nipple, (indicated at g,)

said nippleformed with right and left hand v screw-threads on op osite ends thereof to en gage the. correspond the cylinder and of the chamber c. This nipple may be of any suitable form for the ready engagement of a suitable tool therewith to engage the nipple with the adjacent parts. The jacket-wa desired,- expansion and contraction. I prefer that the head of the-cylinder shall be cast upon the cylinder; The flange Z of the cylinfrom the chamberi into the outlet-channel j,

as indicated at 1*. So, also, the walls of the no ingly-threaded ends of so formed allows, if

erinit the water-to pass valve-chamber c are cored out, as indicated,

for CXttlllPlG, at to allow the'water to pass into the chamber i, the valve-chaniber c be ing provided with a water-chamber t, into which water is admitted in any desired man The frame of the engine is formed with a flange 10, with which the studs n are engaged. It will be perceived that the wateracket wall at its end toward the valve-chamber c is preferably bent on an arc of a circle and that the flange h is of a length suflicient to allow for expansion and contraction or for inequalities of lengths due either to inaccuracies of construction or differences of expansion and contraction; Obviously the flange k of the j acket-wall, beingmade of thin and soft metal, will readily yield to allow for any such inequalities or differences. Ido. not, however, limit myself to the turning of a flange on an arc of a circle.

1t will be seen that in the construction shown and described the end of the cylinder formed with a longitudinal extension on the end thereof adjacent to the valve-chamher, the extension being provided with waterpassages opening into the water-chamber around the cylinder and into the water-chainber around the valvechamber.

What I claim as my invention is l. The combination with an engine provided. with a cylinder and a valve-chamber of a water-jacket wall having flanges at its opposite extremities forming a water-chamber between the jacket-wall and the cylinder, one end of (the cylinder formed with "a flange against which the flan gc of thecorresponding end of the jacket-wall seats, means to secure the corresponding flange u on its seat on the flange of the cylinder, the lange at the oppo site end ofthe jacl et-wall seating against the head. of the cylinder, and separate means to clamp the adjacent flange of the jacket-wall upon the end of the cylinder, said cylinderflange provided with a channel COiUlllUlllCfltring with the waterchamber and the end of the cylinder provided with channels communicating with the water-chainber.

The combination with an engine provided with a frame, a cylimler, and a valvechambcr of a water-jacket wall constructed with a flange at one end and clamped between the end of the cylinder and the valveelia mber, and forming a water-chamber between the jacl etwall and the cylinder, the opposite end of the water-jacket wall formed with a flange seating against the adjacentend of the cylinder, a separate clamping-ring to Clamp the adjacent flange of the jacketwall against the adjacent end of the cylinder, the ire me of the engine provided with means to clamp the said ring in place and to engage the adjacent end of the cylinder with the en gine-frame.
